hey bros, wut's the difference between idling control device and fast idling control device-ar??
the idling control is to adjust the ignition timing, rite?
if so, which is the screw to adjust the air fuel ratio-ar??
correct me if i'm wrong..newbie here.. :P

Hi rikaro, as i stated Fast Idling Control is to control your idling when your aircond kick in where anyone is just to control your normal idling.

A/F ratio screw is not there...sitted opposite your firewall which i dun have a photo of that :lol: :P

hey gavan! i study at tarc also..me in mechanical engineering...drop me a call lah at coll 0166792975..

yeah,in the pic that is the two screw i also adjust..i know one is fast idle..and now only i know the one i always kacao is the idle control devices..
if i not mistaken..fast idle is when ur car is not that hot...it is attach to a vaccum dunno wat stuff to a diaphragm(forgot how to spell it..damn)...u see when ur let ur engine idle like let say 2 minutes..then u hear a "tick" then the rev move or down abit....that is the fast idle screw tap down the lever..u go stand infront of ur engine for like 5minutes u can see the fellow working..correct me if i'm wrong..coz really i forget alot liao luh.,...i think the mixture is somewhere in the down part kua...anyone can show it ??? b]

wah liow eh, small world horr, lolz :P

MY advice is if your carb is OK don't ichy hand go play the setting...

 

[alantan]

now i found the petrol screw....

how should i play wit it to screw it to the optimum?

 

[rikaro]

thanx for replying g88... thanx for sharing the info, guys.. next time i shud try adjusting it myself arleayd...instead of asking my mech to do it for me.... :lol:

hehehehe...my carb is running okie-lar....but i'll still get ichy hands for the love of this DIY thing...:D hopefully i can tune it according to my preference-lar...

hmm..i still can't find the air fuel ratio screw-lar..i'll continue to look for it.. :rolleyes:

oh ya...if i wan more power for my car...wut kinda setting shud i use (using this stock carb) ?? shud i just allow more air into the engine or i shud adjust the fuel supply as well?? :unsure:
